Psalm Chapter 63
David's "my soul thirsts for Thee" in this Psalm was an analogy of how a Conscience that thirsts for righteousness can be compared to a physical body (see Where Is Your Soul?) that is needing water. If lacking, both ache for what must be there for life, water for physical life, The Spirit Of God (see also the Fact Finder question below) for the life to come.
"A Psalm of David, when he was in the Wilderness of Judah.
O God, Thou art my God, I seek Thee, my soul thirsts for Thee; my flesh faints for Thee, as in a dry and weary land where no water is.
So I have looked upon Thee in the Sanctuary, beholding Thy power and glory. Because Thy steadfast love is better than life, my lips will praise Thee. So I will bless Thee as long as I live; I will lift up my hands and call on Thy Name [see What Is God's Name?].
My soul is feasted as with marrow and fat, and my mouth praises Thee with joyful lips, when I think of Thee upon my bed, and meditate on Thee in the watches of the night; for Thou hast been my help, and in the shadow of Thy wings I sing for joy. My soul clings to Thee; Thy right hand upholds me. But those who seek to destroy my life shall go down into the depths of the earth [see Sheol and Hades]; they shall be given over to the power of the sword, they shall be prey for jackals.
But the king [see Israelite Monarchy - The Messiah] shall rejoice in God; all who swear by Him shall glory; for the mouths of liars will be stopped." (Psalm 63-1-11 RSV)
Psalm Chapter 64
David's rise to the responsibility of political power was, on a merely human level, against high odds for success (see Israelite Monarchy - The Origin and The Civil War), but David always recognized that he was merely a servant of an all-powerful King who never loses (see Christ the Conqueror For Peace and The King Of The King Of Kings).
"To the choirmaster. A Psalm of David.
Hear my voice, O God, in my complaint; preserve my life from dread of the enemy, hide me from the secret plots of the wicked, from the scheming of evildoers, who whet their tongues like swords, who aim bitter words like arrows, shooting from Ambush at the blameless, shooting at him suddenly and without fear.
They hold fast to their evil purpose [see Evil Means Fool]; they talk of laying snares secretly, thinking, "Who can see us? Who can search out our crimes? [see Glass Houses] We have thought out a cunningly conceived plot." For the inward mind and heart of a man are deep!
But God will shoot His arrow at them; they will be wounded suddenly. Because of their tongue He will bring them to ruin; all who see them will wag their heads.
Then all men will fear; they will tell what God has wrought, and ponder what He has done. Let the righteous rejoice in The Lord, and take refuge in Him! Let all the upright in heart glory!" (Psalm 64:1-10 RSV)
Psalm Chapter 65
David's "Blessed is he whom Thou dost choose and bring near, to dwell in Thy courts! We shall be satisfied with the goodness of Thy House, Thy Holy Temple!" was spoken before the Temple in Jerusalem was built (i.e. it was constructed in the time of David's son Solomon, after David had died) was a prophecy of the ultimate meaning and purpose of The Lord's Temple (see The House Of Prayer Of All Nations)
"To the choirmaster. A Psalm of David. A Song.
Praise is due to Thee, O God, in Zion [see Zionism]; and to Thee shall vows be performed, O Thou who hearest prayer! To Thee shall all flesh come on account of sins. When our transgressions prevail over us, Thou dost forgive them. Blessed is he whom Thou dost choose and bring near, to dwell in Thy courts! [see Court] We shall be satisfied with the goodness of Thy house, Thy Holy Temple!
By dread deeds Thou dost answer us with Deliverance, O God of our salvation, who art the hope of all the ends of the earth, and of the farthest seas; who by Thy strength hast established the mountains [see Christ The Creator], being girded with might; who dost still the roaring of the seas, the roaring of their waves, the tumult of the peoples; so that those who dwell at earth's farthest bounds are afraid at Thy signs; Thou makest the outgoings of the morning and the evening to shout for joy.
Thou visitest the earth and waterest it, Thou greatly enrichest it; the river of God [see the Fact Finder question below] is full of water; Thou providest their grain, for so Thou hast prepared it. Thou waterest its furrows abundantly, settling its ridges, softening it with showers, and blessing its growth. Thou crownest the year with Thy bounty; the tracks of Thy chariot drip with fatness. The pastures of the wilderness drip, the hills gird themselves with joy, the meadows clothe themselves with flocks, the valleys deck themselves with grain, they shout and sing together for joy." (Psalm 65:1-13 RSV)
Psalm Chapter 66
"To the choirmaster. A Song. A Psalm" (see The Harp String Verses) plainly states how the Psalms were songs and music, but they were far more. The Psalms are rich in accounts of Bible History, foresights of Prophecy and righteous principles of Christian Living.
"To the choirmaster. A Song. A Psalm.
Make a joyful noise to God, all the earth; sing the glory of His Name; give to Him glorious praise! Say to God, "How terrible are Thy deeds! So great is Thy power that Thy enemies cringe before Thee (e.g. see "Strong Is He Who Has Come Down"). All the earth worships Thee; they sing praises to Thee, sing praises to Thy name." [Selah]
Come and see what God has done: He is terrible in His deeds among men. He turned the sea into dry land [see also Why Did Christ Put Moses To Death?]; men passed through the river on foot. There did we rejoice in Him, who rules by His might for ever, whose eyes keep watch on the nations - let not the rebellious exalt themselves. [Selah]
Bless our God, O peoples, let the sound of His praise be heard, who has kept us among the living [see What Happens When You Die?], and has not let our feet slip. For Thou, O God, hast tested us; Thou hast tried us as silver is tried. Thou didst bring us into the net; Thou didst lay affliction on our loins; Thou didst let men ride over our heads; we went through fire and through water; yet Thou hast brought us forth to a spacious place.
I will come into Thy house with burnt offerings; I will pay Thee my vows, that which my lips uttered and my mouth promised when I was in trouble. I will offer to Thee burnt offerings of fatlings, with the smoke of the sacrifice [see Burnt Offerings to understand the related origin of the word holocaust] of rams; I will make an offering of bulls and goats. [Selah]
Come and hear, all you who fear God, and I will tell what He has done for me. I cried aloud to Him, and He was extolled with my tongue. If I had cherished iniquity in my heart, The Lord would not have listened. But truly God has listened; He has given heed to the voice of my prayer. Blessed be God, because He has not rejected my prayer or removed His steadfast love from me!" (Psalm 66:1-20 RSV)
Psalm Chapter 67
This Psalm is also prophetic in that it awaits a time when, after the return of Jesus Christ (see What Is Jesus Christ Doing Right Now?) all the earth will joyfully come to know The Lord e.g. "It shall come to pass in the latter days that the mountain of the house of The Lord shall be established as the highest of the mountains, and shall be raised up above the hills; and peoples shall flow to it, and many nations shall come, and say: "Come, let us go up to the mountain of The Lord, to the house of the God of Jacob; that He may teach us His ways and we may walk in His paths." For out of Zion shall go forth the law, and the word of The Lord from Jerusalem. He shall judge between many peoples, and shall decide for strong nations afar off; and they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war any more" (Micah 4:1-3 RSV).
"To the choirmaster: with stringed instruments. A Psalm. A Song.
May God be gracious to us and bless us and make His face to shine upon us, [Selah] that Thy way may be known upon earth, Thy saving power among all nations. Let the peoples praise Thee, O God; let all the peoples praise Thee! Let the nations be glad and sing for joy, for Thou dost judge the peoples with equity and guide the nations upon earth. [Selah]
Let the peoples praise Thee, O God; let all the peoples praise Thee! The earth has yielded its increase; God, our God, has blessed us. God has blessed us; let all the ends of the earth fear Him!" (Psalm 67:1-7 RSV)
